If you want to OC with hardware you can easily obtain new, you have to pay a 170 dollar premium.
Even if we limit the argument to CPUs that are effectively identical in all ways, except for being unlocked, and further limit ourselves to Haswell/LGA1150, we are still looking at a 60 dollar gap between the i5-4430 and the i5-4570K. That's three times as much as 20, and a 33% premium over the cost of the 4430.
And of course, this limitation ignores the fact that many tasks still don't need a quad core as much as they would benefit from a fast dual core (possibly w/HT). If a low end i3 or Pentium could OC, it could be made to match an i5 K in many of these tasks for half the price, or less.

Sandy and Ivy parts had four multipliers above their turbo states that could be used for OCing.
These no longer exist and that's what this article is about.

Before Sandy, there was no way to prevent significant OCing on a motherboard with adjustable reference clocks and a PCI/AGP/PCI-E lock.
In 1995, I bought a Pentium 75MHz and without touching the multiplier, ran it at 100MHz simply by moving the FSB jumper from 50MHz to 66MHz. The Pentium 75 cost less than half the Pentium 100 at the time.
In 1997, I bought a Pentium MMX 200, and ran it at 266MHz by upping the multiplier by one. There was no desktop 266MHz Pentium.
In 2000, I bought an Athlon 700MHz, and with a bit of hardware tweaking was able to run it at an 8.5 multipler with a 112MHz FSB, or 950MHz, on a board that didn't even have a PCI/AGP lock. Again, I saved myself hundreds of dollars here.
From 2001 to 2004 I had about a dozen Socket A Athlons and Athlon XPs, and I was always able to buy some of the cheapest parts in a series, and was always able to make them run faster than the highest end officially released part.
In early 2004 I picked up my first Athlon 64. Because multiplers were locked, and most platforms available at release did not have PCI/AGP locks. So for the first time in about 10 years, I couldn't OC more than ~10% or so. Release of the NForce3 chipset, and later a revised VIA K8T chipset, with these locks let me get some pretty damn impressive OCs out of dirt cheap parts once again.
From 2004 to 2006 I OCed a pile of A64s and a few opterons, again all lower end models. I had an NF4 DAGF that cost me 70 dollars, and was able to get 50% OC out of my 3000+ Venice, a 65 dollar part. I had a system that could go toe to to with some of the fastest single core stock parts at the time (all 500 dollars +), that cost me under 150 dollars for CPU+mobo+RAM.
In early 2007 I switched back to Intel, because Core 2 had been released. I sure as hell wasn't going to spend hundreds of dollars on high-end parts, so I bought a Pentium E 2140 for $70, and DFI Blood Iron for about the same price. It wasn't even difficult to get a 100% OC on this chip, with the stock cooler. So yeah a 150 dollar board + CPU combo was match a stock QX6850s that cost 1k for the CPU alone. I later took a few E8400s to 4GHz+, and my best W3350 (Xeon equivalent of a Q9450) also managed 4GHz, though on a much better board than the Blood Iron (which could not handle anywhere near 500MHz FSB with a Yorkfield quad).
In very early 2009 I grabbed an LGA-1366 setup, and immediately took an i7 920 C0 to 3.8GHz (from 2.66). It was not a budget platform, but I was still able to buy the lowest end parts made for the socket, and generally match what the highest end parts could do. I ran an i7 920 D0 at 4.2GHz (nearly a 60% OC) 24/7, for years, on a budget board, with a 50 dollar air cooler, and the least expensive memory I could find.
Since that time, I've been limited to buying K parts to OC, and OCing has thus gotten a lot more expensive, for relatively less performance gain. It's not a huge problem for me personally, as my uses are more varied and demanding that what they once were, and I've had to buy hex cores that can all OC anyway (a 2700k from Intel's retail edge is probably the last desktop quad core I'll ever put in one of my systems), but there are times that I want build a super budget box for myself, or someone else, and have to reconsider because there are no longer any
budget CPUs that will suffice for the same kinds of uses I once bought them for. Seriously, I used to be able to make fairly high-end gaming systems for 500-600 dollars by spending 50%+ of the budget on the GPU, and overclocking the snot out of everything else
. Can't do that any more, not even with AMD.
